MEANS FR TREATING KEROSENE OR THE FOR USE IN HYDROCARBON-ENGINES. f

a citizen of the United States, residing at La Fayette, in the county of Tippecanoe and State of Indiana, have invented certain new and useful Improvements in Means for Treating Kerosene or the like for Use in ing is aspeciication. v

vMy invention relates to a means by which kerosene or similar oil may be heated to the necessary temperature and introduced while at suchv temperature into the cylinders of vhydrocarbon engines, so that kerosene can be used as the motive power for such engines.'

The object of my invention is to provide means whereby the exhaust gases are utilized to heat the kerosene, and also whereby more or less of the total amount of the exhaust gases may be utilized to heat the oil, so that the temperature to which the oil is heated 1 may be regulated or lkept uniform'irrespective of the amount of the exhaust gases or their temperature.

With the foregoing and other objects in view my invention consists in certain constructions, combinations and arrangements of parts, the preferred form of which will be first described in connection with the accompanying drawings and then thev invention particularly pointed out in the appended claims.

Referring to the drawings wherein the same part is designated by the same reference numeral wherever it occurs Figure 11 is a side elevation of a standard type of hydrocarbon engine equipped with the preferred form of my invention; Fig. 2 is a section through the exhaust manifold taken .on line 2, 2 of Fig. 1, and Fig. 3 is a section taken on line 3-3 of Fig. 1.

' 5 designates'the cylinders of a standard type of hydrocarbon engine having the usual intake pipes 6 connectingan ordinary carbureter 7 to the intake ports. are illustrated as of an ordinary standard type and form no part of my invention. They are shown merely for the' purpose of giving a specific 'application of one form-of my invention to a hydrocarbon engine;A

In the preferred form of my invention I construct the exhaust'manifold 8 in the form of a double pipe as shown, whereby there are two passages 9, 10 .formed for the exl- Specication of Letters Patent.

haust gases, the gases entering each passage of the manifold through openings 11 common 'to both passages. Each of these openings is preferably surrounded by a flange 12, which are adapted to be bolted to the cylinder and surround an exhaust p'ort whereby' the hot exhaust gas will pass directly from the engine into the manifold.

Located in one of the passages of the manifold as 10 is a heater by which the oil 65 supplied thereto can be raised to the desired temperature. In the form of my invention shown this heater is in the form of a coil 13 which extends through the passage 10 and consequently is in position to be impinged upon by the hot gases as they enter the passage through the openings 11 direct4 from the exhaust ports.

14 vdesignates the intake end of the coil and the outlet end is connected `by a longi- 7 5 tudinally extending pipe 15 to the intake plpes closely adjacent the intake ports.

As the amount of heat supplied to the coil will vary both with the volume ofexhaust gases and the atmospheric conditions, 80. everything else being equal, it is highly de- 4 sirablev and in fact essential to obtaining'the maximum efficiency under all the various working conditions under which the engine must operate, that means be provided for 35 regulating the volume vof gas flowin'g through the passage 10. In order to effect this I have provided a pair of butterflyf .valves 16, 17, mounted on a shaftlS provided with a crank arm 19 adapted to' be 90 a singley pipe 20. In this construction it will loe/seen that as the shaft 18 is turned tol open one of the butteriy valves, theother butteriy valve will be closing. Consequently'the amount of gas passing through the passage ways 9 and 10 willbe regulated. 105

If for instance the oil in the heater 13 is the valve 17 lwhich operates to open the jvalve 16. Consequently less gas will pass 1i through the passageway l0 and thus the oil will be heated to a less extent. When the oil is not delivered to the engine at a sufficiently high temperature, then the movement of the valves is reversed.

It is understood of course that the engine is to be started by gasolene in the ordinary way, and for this purpose a carbureter 7 is provided.Al Yhen the manifold is heated up to a suliiciently high temperature then the supply of gasolene to the carbureter is cut ofl" and kerosene supplied to the heater coil and the motor power consequently changed from asolene to kerosene.4 It will be further o served that the necessary air to mix with the kerosene will be obtained through the air valve in the carbureter and the intake pipe 6. y

I realize that considerable variation is possible in the details of construction and arrangement of parts without ldeparting from the spirit of my invention, and I therefore do not intend to limit myself to the specific form shown and described.

Having thus described my invention what I claim as new andv desire to secure by Letters Patent is:

1. The combination with a hydrocarbonn immediately prior to entering the cylinder7 and means for directing the exhaust flame toward or from the heater to regulate the temperature to which the oil is to be heated as desired. y

2. The .combination with a hydrocarbon engine having inlet and exhaust ports with pipes connected therewith, of an exhaust manifold therefor in close proximity to said ports having a pair of passage ways therethrough, the manifold being provided with openings extending into both passage ways with said openings connected to the exhaust port of the engine, an oil heater located in one of the passage ways with one end adapted to deliver heated fuel after passing through the same immediately t-o the intake pipe at a point adjacent the intake port of the 'engine whereby the oil willv be cracked in the heater and delivered in cracked condition immediately to the inlet port at substantially the temperature at which it was cracked where it mixes with air at substantially atmospheric temperature.-

3. The combination with a engine, of an exhaust manifold therefor having a pair of passage ways therethrough, the manifold being provided with openings extending into both passage ways with said openings connected to the exhaust ports of the engines, a heater located in one of the passage ways, a pair of valves mounted on a common shaft, one for each passage way,

with said valves arranged at substantially` hydrocarbon right angles to each other whereby as oney in presence of two. witnesses.
